Abstract

An adjacent sequence iteration method for designing a diffractive element with function of controlling wavefront propagation is presented, and a binary optical element for focusing a diode laser beam in a long focal depth is designed with this method, fabricated by means of photolithography and ion-etching techniques. The simulation calculated with the designed element indicates that the design is successful, and the experiment results of long focal depth by testing the produced element are consistent with the design requirements.
